An AmmoLyt

®

Plus

700 IQ sensor ready to measure requires a 

reference electrode and an ion sensitive electrode for the main 
parameter, ammonium. The electrodes are screwed into the electrode 
support. The electrode support has two receptacles for this.

Automatic potassium

compensation

With the aid of the automatic potassium compensation, the influence of 
potassium ions on ammonium measurement due to measuring 
technique is compensated for during measurement. To determine the 
potassium concentration, the AmmoLyt

®

Plus

700 IQ is equipped with a 

potassium electrode for compensation.
